Hiring a private commercial counseling service is another way to get help in doing business with the government. The good ones can offer great personalized assistance, but will cost you some kind of money, flat fee, percentage of contract, retainer plus costs, or some combination.
If you decide to use this method, try to find a service that is accustomed to working with small companies. And remember: Buyer beware. If a service tells you that it can guarantee you contracts, keep looking. Check references and talk to some of the government people that the service has worked with.
You can find a commercial counseling service through word of mouth or by searching on the Internet. Sometimes a Small Business Specialist will be able to recommend a good one.
